Insert the pressure piece into the actuator
the following: The thread of the pressure piece spindle and the
hand wheel spindle must engage with each other
→
Turn the hand wheel to the Open position
→
Position and tighten the screw (for RV50 Allen-type, for RV70/
RV110 hexagonal) on the side of the actuator

→
Put the actuator / diaphragm on the body with correct alignment
(so that the markings made previously align).
→
Tighten the diagonally opposed body screws / nuts until there
is visible, uniform mechanical contact between the valve body,
diaphragm and actuator
→
Tighten the diagonally opposed body screws / nuts twice with a
quarter turn and using the same torque in each case.
test for leak-tightness / valve function
Warning!
danger of injury through egress of flow medium.
▶ Tighten the body screws / nuts sufficiently.
Applying an unnecessary degree of force to tighten the
body screws / nuts leads to increased wear and therefore
shortens the service life of the diaphragm.
If the valve leaks when the medium pressure rises:
→
Tighten the diagonally opposed body screws / nuts by a one-
eighth turn until the valve no longer leaks.

This procedure ensures that the diaphragm and the pressure piece
are optimally aligned to each other and the valve function is ensured.
